CalTopo offers many tools designed specifically for backcountry mapping applications. These tools include numerous drawing and measuring tools, profiles of terrain and elevation for evaluating a route and making a detailed plan, slope angle shading for assessing winter travel risks, and many other custom overlays and layers.

Terrain Profile can be generated from any line and includes detailed information from elevation, to slope angle, to canopy and ground coverage, and much more. This information can be used for planning anything from day trips to week long summer and winter backpacking trips.

Analytic tools like slope angle shading can be used to gain insights into backcountry hazards, and plan fun ski routes.

Draw on the map anywhere you need to get detailed point, line, or polygon data, such as calculating the area of a tract of land, the distance of a hike, or weather forecasts for the coming day
